What is Pterygium?
Pterygium is a fibrovascular growth on the conjunctiva (white part of the eye) which extends towards the cornea. They develop from excessive ultraviolet (UV) light exposure. This condition is very common in countries along the equator. Usually seen in individuals who spend a considerable amount of times outdoors such as fisherman, transportation drivers, golfers, farmers etc.
- Ocular surface irritation
- Dry eye
- Foreign-body sensation
- Blurring of vision from irregular astigmatism (advanced stage)
If required, pterygiums can be removed surgically. Removal of pterygium will likely be advised if it is growing far enough onto the cornea to threaten your line of vision. Pterygia may also be removed if they cause a persistent foreign body sensation in the eye, or if they are constantly inflamed and irritating. In addition, some pterygia grow onto the cornea in such a way that they can pull on the surface of the cornea and change the refractive properties of the eye, causing astigmatism. Removing the pterygium may decrease astigmatism. Newer techniques practiced at RANU EYE SPECIALIST such as EXCISION OF PTERYGIA AND CONJUNCTIVAL AUTOGRAFTS USING TISSEL GLUE can reduce the recurrence to less than 7%. Immediately after the removal of the pterygium, your eye will be patched for 24 hours to allow the surface of the eye to heal. Majority return to work almost immediately. Eye drops will be required for about a month.
